Well I became a Trek fan around 1975 when the show went into heavy syndicated airplay. I was 8 or 9 years old, and the show became a huge part of my life. I had the tie-in toys, games and action figures. I had Kirk's uniform shirt (made the mistake of wearing it to school, but that is a story for another time...). Well I loved the original ship too. It was imprinted on my brain. In 1979 when I saw STMP for the first time, I hated the sets, the costumes, and the new look of the ship. It was not until I saw "The Wrath of Khan" and the re-lighted and decorated sets, that I re-evaluated The Enterprise as seen in "The Motion Picture". That engine room set is still impressive. I don't think they have ever topped it. The ship as seen in the first two films seemed to me like it could have been a real functional spaceship. The original series ship left a lot to the imagination as far as things like the control panels, and other props. It's the realism of the movie ship this makes it my personal favorite.
